The path of travel of the gases as they progress around and around the chamber will be so long that a very intimate mixture of them will result and a high production of acid. Hence a low cost in chambers, which may be made smaller per unit of capacity.

Having now described my invention, what I claim, and desire to secure by Letters Patent, is-

In a sulfuric-acid apparatus the combination of a series of circular or substantiallyA circular chambers connected by pipes, each chamber having a single inlet-pipe, and a single outlet-pipe, the single inlet-pipe of each chamber entering it at the side near the top only and tangentially, and the single outletpipe descending and leaving said chamber from the center of the bottom, whereby gases are admitted at the top of the chamber, permitted to rotate in the chamber, and as' they cool and descend, drawn ot from the center of the bottom of the chamber in a downward direction, substantially as described.
